Description

Oil press lifting platform convenient and quick to adjust Technical Field The utility model relates to the technical field of oil presses, in particular to an oil press lifting platform convenient and rapid to adjust. Background The hydraulic press is used as core forming equipment which takes hydraulic oil as a power medium and drives an oil cylinder/piston to reciprocate through a hydraulic pump, and the working performance of the hydraulic press directly influences the processing efficiency and the accuracy of processes such as stamping, forging and the like. In the prior art, in order to avoid defects of the pressurized parts, the oil cylinder needs to slowly descend and ascend at a constant speed, so that the processing efficiency is affected. Aiming at the defects, the hydraulic press lifting platform convenient and quick to adjust is provided. Aiming at the defects, the hydraulic press lifting platform convenient and quick to adjust is provided. Disclosure of utility model The utility model aims to solve the defects in the prior art, and provides an oil press lifting platform convenient and rapid to adjust. In order to solve the problems existing in the prior art, the utility model adopts the following technical scheme: The utility model provides a make things convenient for quick adjustment's hydraulic press lift platform, includes hydraulic press frame, fixed mounting at the hydro-cylinder on hydraulic press frame top, sliding fit at the stand of hydraulic press frame inner wall, still includes: The lifting platform comprises a mounting plate fixedly mounted at the telescopic end of the oil cylinder, four through holes formed in the upper surface of the mounting plate in a rectangular array, guide posts respectively slidably mounted on the inner walls of the four through holes, a pressing plate fixedly mounted at the lower end of the guide post and a baffle fixedly mounted at the upper end of the guide post; The platform speed adjusting structure is composed of an oiling component arranged above the oil press frame and an induction component arranged on the upper surface of the mounting plate; The oil injection assembly comprises a first oil injection pipe and a second oil injection pipe which are respectively and fixedly arranged at the oil inlet end of the oil cylinder, a first electromagnetic valve and a first flow regulating valve which are sequentially connected in series with the outer wall of the first oil injection pipe, and a second electromagnetic valve and a second flow regulating valve which are sequentially connected in series with the outer wall of the second oil injection pipe; The induction component comprises a contact switch fixedly arranged on the upper surface of the mounting plate, and the contact switch is positioned right below the baffle plate Preferably, the contact switch is used for controlling the opening and closing of the first electromagnetic valve and the second electromagnetic valve.
